Yahoo! used its time at SXSW interactive this week to announce a huge and pretty unexpected new musical venture: the "Yahoo! on the Road" tour. This spring, the company will official kick off a six-week, international trek with some of the biggest names in the business. Amongst the musicians slated to perform are Jay-Z, Kendrick Lamar, J. Cole, Macklemore and Ryan Lewis and “special guests” Justin Timberlake, Frank Ocean and Trey Songz.

While a definitive line-up and schedule has yet to be released, the Yahoo! on the Road site provides the dates below and promises 32 performers, 10 comedians and “1 yodeler.”
